Does surface tension above boiling temperature still exist?

Does surface tension above boiling temperature still exist? It remains unclear whether boiling metal surfaces can still show surface tension, says Prof Dr-Ing. Jörg Volpp, Associate Professor at University West, Trollhättan in Sweden. Modern manufacturing methods involve thermal processes that heat metal materials to temperatures exceeding their boiling point. This is common in various techniques, such as welding, cutting, and additive manufacturing. Since the quality of the outcome is also defined by surface tension, gaining a better understanding of how these extreme conditions affect surface tension is highly desirable.
